Unity HUD does not work with Java applications

The Unity HUD is not usable in Java applications. I tried to use the Unity Launcher in "Freemind" and "Freeplane" but none of them did show any menu items in the HUD.

reproduce:

1) start a Java application (in my case Freemind or Freeplane)
2) lookup a menuentry in the applications menus and remember the name
2) press Alt and try to search the menuentry you just looked up

expected result:
the menuentry should show up in the HUD

actual result:
the HUD does not work at all in Java applications
